Here's an interesting trend within the world's Bitcoin exchanges. People with real-money jobs can't resist the thrills of trading the fake stuff as if it were an international currency. Reuters dug up some sources within the world's biggest financial institutions found that people who work at Morgan Stanley and Goldman Sachs are trading Bitcoin from work. One source estimated that 90 percent of traders have bought and sold the currency.

It's not all that surprising that traders have embraced the anarchic, stateless fiat. These are the very people who bundled billions of debt into a mammoth bubble of unstable financial products. They're sort of the same thing. [Reuters]
